I'd guess $200-300. At least that is what they used to charge last time I checked. Ridiculous if you ask me. My Dad has a 2005 300c and has never updated his Nav unit.

Maybe for the lifetime subscription but not every time you want/need to update the navigation maps. At that price it wouldn't make sense cuz you can buy a mobile GPS for that price with lifetime updates.

It looks like the Overland does have the blue piping around the seats - I hope the Summit doesn't. Really like the chocolate interior. also I prefer those wheels to the ones that are upgraded on the Summit.
